## Summary

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 757 airplanes. This proposed AD was prompted by a report of a broken forward support fitting at the inboard track of the inboard flap. This proposed AD would require repetitive inspections of the forward support fitting assemblies of the inboard track of the left and right inboard flaps for cracking, and corrective actions if necessary. We are proposing this AD to detect and correct cracking of the forward support fitting assembly, which could result in loss of inboard flap control and subsequent loss of airplane control.
